That device is not supported by b43. As it now stands, b43 requires a device
with the SSB interconnect, which the BCM4313 does not have. If you did fix b43
to operate without the SSB, then you would still have no support for N PHY. That
one is being worked on so that N PHYs with SSB can be supported.

My interpretation of the "partially supported" statement is that bleeding-edge
compat wireless has been backported that far.

My latest pull of wireless-testing has 2.6.37-rc1 from November 1. It includes
brcm80211.
